Lau 38251302M Blower Assembly
The Lau 38251302M Blower Assembly, specifically the DD9-9A double inlet model, is a heavy-duty direct drive blower designed for high-static efficiency in furnace and air handler applications. This unit features a 9-9/16" diameter wheel with a 10-1/4" width, optimized for consistent airflow delivery across residential and light commercial HVAC systems. Constructed with a G90 galvanized steel housing, the assembly resists corrosion while maintaining structural integrity under high-RPM operation. The 1/2" bore size and CW rotation (clockwise from the lead end) allow for seamless HVAC blower motor replacement in standard direct drive configurations. Engineered to reduce vibration and operational noise, this assembly ensures proper air handler blower wheel balance, preventing premature bearing failure in the drive motor. Its compact 11-7/8" x 10-1/4" footprint makes it an essential centrifugal blower fan component for technicians requiring precise furnace blower assembly dimensions and reliable static pressure performance.
- Dynamic Balance: Precision-engineered wheel reduces harmonic vibration and extends the life of the blower motor.
- Industrial Grade Housing: The Lau DD9-9A utilizes heavy-gauge galvanized steel to prevent rust and frame distortion.
- Direct Drive Efficiency: Eliminates the need for pulleys and belts, reducing maintenance requirements and mechanical loss.
- Universal HVAC Compatibility: Standardized bore and rotation specs allow this OEM replacement blower to fit multiple furnace and air handler brands.
Frequently Asked Questions
What is the importance of the 1/2" bore size on this Lau assembly?
The bore size must match your motor shaft diameter exactly. A 1/2" bore ensures a secure press-fit or setscrew attachment, preventing slippage and shaft scoring during high-torque startups.
How do I confirm the CW rotation is correct for my system?
Rotation is determined by looking at the blower from the motor/lead side. If your current wheel spins clockwise from that perspective, the Lau 38251302M is the functionally correct match for your discharge orientation.
Can this blower assembly be used in high-static pressure environments?
Yes, the centrifugal fan design is specifically engineered to overcome the resistance of ductwork and evaporator coils, maintaining rated CFM even as static pressure increases.
